L6227PDTR

Overview

The L6227PDTR is a DMOS dual full bridge motor driver designed for control applications, realized in BCD technology. It integrates isolated DMOS power transistors with CMOS and bipolar circuits. The device features two independent constant off-time PWM current controllers for chopping regulation. It supports an operating supply voltage from 8 V to 52 V and delivers a peak output current of 2.8 A (1.4 A DC). The typical RDS(ON) is 0.73 Ω at Tj= 25 °C. Operating frequency reaches up to 100 KHz. It includes non-dissipative overcurrent protection on high-side MOSFETs, thermal shutdown, cross-conduction protection, undervoltage lockout, and slow decay synchronous rectification.

Procurement Notes

Verify the specific suffix 'PDTR' corresponds to the PowerSO-36 package with slug-up configuration and tape-and-reel delivery format. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and thermal pad specifications required by your PCB layout design.

Selection Notes

Select this component when a dual full bridge configuration with integrated current control is required. It is suitable for applications needing high-side non-dissipative protection and synchronous rectification. Consider the PowerSO-36 package for thermal performance and the 8V-52V voltage range compatibility.
